When Models Won't Converge, Project Timelines Pay the Price

In nonlinear finite element simulations, convergence problems remain one of the most common obstacles to obtaining accurate and reliable results. These issues typically emerge in models involving contact, nonlinear materials, or unstable geometries. Understanding their root causes, and knowing how to resolve them, is essential for reducing simulation time, improving model robustness, and increasing overall project efficiency.

Webinar Scope

This webtraining session offers a high-level overview of the strategies and tools available in Abaqus for addressing convergence problems. We will examine how Abaqus solves nonlinear problems, discuss best practices for building robust models, and show how to identify and correct errors that lead to divergence. The session draws on years of experience resolving convergence challenges in customer projects.
